Karlheinz Stockhausen (1928-2007): Opus '70, per suoni elettronici, pianoforte, viola elettrificata e percussioni (1969). Registrazione effettuata il 10 e il 14 Dicembre 1969 allo studio Godorf, Colonia. This classic live electronic improvisation work (which grew out of Stockhausen's Kurzwellen) is actually a great noisy atonal tribute to Beethoven's Opus 212b. Stockhausen's Opus 1970 was composed to mark the 200th anniversary of Beethoven's birth, but curiously suppressed in the official list of Stockhausen works. The players activate tapes containing abstract fragments of Beethoven's music as they perform and improvise in response, with Stockhausen electronically processing and mixing the group's output. “Based formally on the composition of “Kurzwellen“: material is obtained from a regulating system (radio short waves), selected freely by the player and immediately developed. By “developed“ is meant: spread, condensed, extended, shortened, differently coloured, more or less articulated, transposed, modulated, multiplied, synchronized. “ (Karlheinz Stockhausen). Parte I Parte II (start at 28'.23'') Aloys Kontarsky, pianoforte Johannes G. Fritsch, viola elettrificata Harald Bojé, elektronium Rolf Gehlhaar, tam tam Karlheinz Stockhausen, klangregie. *** The music published in our channel is exclusively dedicated to divulgation purposes and not commercial.
